966# basically look for the first lseek command (we do the strings/grep because
967# sometimes the function call is _llseek or something) and steal the 2nd
968# parameter. here is an example:
969# root@vapier 0 pdv_unpack # strings hldsupdatetool.bin | grep lseek
970# lseek
971# root@vapier 0 pdv_unpack # strace -elseek ./hldsupdatetool.bin
